I put my 10 month old down for a nap this afternoon. She was absolutely howling when I put her in her cot (something she does quite often) but instead of going in and out every couple of minutes to cuddle and comfort her as I usually do, I let her cry herself to sleep. It took 8 minutes in total before she was out like a light. However I now feel huge guilt and sadness that I could have really upset and traumatized her by not responding to her cries. I was just so exhausted and desperate for some alone time. Have I been cruel?
